ROTY VALVE AND MANIFOLD.

Specification of Letters Patent.

Patented Apr. 36, 1.91..

Application filed June 27, 1917. Seriai K0 17732 7.

To all whom it may concern Be it known that we, Ror W. PAUL and LUTHER L. CLARK, citizens of the United States, residing at Charleston, in the county of Harper and State of Oklahoma, have invented new and useful Improvements in Rotary Valves and Manifolds, of which the following is a specification.

This invention relates to a rotary valve and manifold for an internal combustion engine, and an object of the invention is to of an internal combustion engine, and adapted to have communication with the intake and with the exhaust.

With the above and other objects in view,

the invention consists in the novel construction and arrangement of elements hereinafter described and claimed, and illustrated in the accompanying drawings in which 5-- Figure 1 is a vertical longitudinal section through the valve casing.

Fig. 2 is a horizontal section.

Fig. 3 shows a detail of construction described below.

e have illustrated a portion of an engine including a plurality of cylinders 10, 11,12 and 13 having communication with a valve casing by means of ports 15, 16, 17 and 18. The valve casing includes an inner cylindrical portion 20 surrounded by a water jacket 21, and within the bore 20, a rotary valve member 22 is positioned, this valve member being driven by means of a gear 24 operated in any suitable manner at one half the speed of the engine shaft.

The valve 22 is provided with outwardly extending annular portions or rings 25 which operate within channels 26 formed in the wall of the casing, these channels being provided with annular grooved members 27 of a cross section substantially correspond ing with the cross section of the ring 25 and adapted to prevent leakage at the points indicated.

lExtending longitudinally of valve member 22 is an inner concentric tube 30 constituting a fuel inlet pipe and having connection with ports 31 extending radially of the valve member in order to provide for the admission of fuel from the intake 30 through the ports 15, 16, 17 and 18 when said ports 31 register with the ports just mentioned.

Other series of ports are provided in valve member 22, these ports being designatedfit, and'the latter provide for the exhaust from the several cylinders when they register with ports 15 to 18 inclusive. A longitudinally extending chamber 36 is concentric with the inner wall of the valve member and said chamber 36 provides for the passage of the exhaust gases from ports 34 to an exhaust chamber 36 located at one end and leading to a mufier or the like.

The inlet ports are positioned around the circumference of valve member 22 in suitable relation to each other so that the proper cylinders will receive theircharge insuccession. The outlet ports 34 are correspondingly positioned. The manner of spacing the ports in order to meet the conditions indicated is well understood and requires no further description. Below the upper section of the valve casing a thin plate 40 may be provided and this plate may be removed for the purpose of taking up wear.

We claim 1. In a device of the class described, a valve casing, a plurality of cylinders provlded with ports having communication with the casing, a rotary valve member extending across the ends of the cylinders and mounted within the casing, an inner tubular member extending through the valve member and having communication at one end with a fuel inlet; a plurality of annular members extending from the valve member, said casing being provided with channels for the accommodation of the annular members and said valve member being provided with ports extending through the annular members and communicating with the inner tubular member and the inlet, and said valve member being provided with exhaust ports.

2 lln a device of the class described, a caslng provided with annular grooves on the inner portion thereof, channeled members positioned within the grooves, a rotary valve member within the casing, annular proecting members carried by.the valve member and cooperating with the channel members, a tubular member extending through the body of the valve member and having communication at one end with a fuel inlet, a plurality of inlet ports extending through the annular members on the valve and comthe end of the casing, and means for drivmunicating with the inner tube, a lurality ing'said valve member.

ofexhaust ports in the valve mem er each In testimony whereof we afiix our signa- 10 in clrcumferentlal almement wlth the corretures.
